Abstract


This paper reports the development of the soil spectral library using Analytical Spectral Device (ASD) FieldSpec 4 Spectroradiometer with 350-2500 nm wavelength band. In this experiment we have used visible and Near-infrared band. The particular instrument is used to analyze the chemical properties of soil such as Carbon (C), Nitrogen (N), Phosphorus (P), and physical properties of soil such as soil texture (sand, silt, clay) and moisture content. It is observed that physical and chemical properties can be analyzed using hyperspectral band. The database used for experiment have 80 samples of soil which are collected from Aurangabad, Jalna, Parbhani, Hingoli, Nanded, Lature, Osmanabad and Beed from Marathwada region of Maharashtra state with their GPS coordinates. Linear Discriminant Analysis (LDA) technique is implemented for classification of soil spectral signature of chemical properties. Soil texture of Marathwada region comes under the silt clay loam. We got the 100% accuracy of Phosphorus content, where as Carbon and Nitrogen content found 75%, 87% respectively for Marathwada region.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
